tar & ulimit are pissing me off.

ulimit is not undocumented, it is not an independent command, it is a
bourne shell builtin, see that man page for info. The csh has a corres-
ponding builtin command 'limit'. BTW, ISC has an interesting bug in the
csh limit function. If you set it unlimited instead of getting what you
would expect everything exceeds your limit!! Sounds like a variable that
needs to be unsigned is not declared so somewhere.

As another poster noted, you need to rebuild and run a new kernel with this
parameter change to get any effect. As root you can set the ulimit and then
issue the uucp command and you should have no problem.

This is great!! I am not surprised you get a checksum error with a command
like this, what you have when you are done is just part 10!! Try replacing
the '>' with '>>' and everything should work fine :-}!!

Ain't Unix Grand :-} :-}!!
